Icono en una Cabecera de ALV

[turbo1959]

Buenos dias. Tengo un ALV que en la cabecera del informe quiero sacar un icono.

Lo hago de la siguiente manera:

INCLUDE <icon>.
TABLES icon.
DATA icon_mrp LIKE icon-id.

Y cuando voy a sacar las cabeceras del ALV:

WRITE icon_display_more AS ICON TO icon_mrp.

i_heading-typ = 'S'.
i_heading-key = 'Icono :'
i_heading-info = icon_mrp.

Debugando me sale en icon_display_more el dibujito del icono, pero en ino_mrp @1E@

Y al sacarme la cabecera me sale @1E@ en vez del dibujito del icono.

En que me estoy equivocando?

Gracias y Saludos

Yo creo que aquí.
En los ejemplos del WRITE qué tipo de datos declara para el WRITE AS ICON?
